【Abstract】 Processing technology of PA/PP core-sheath composite fiber is studied and the difficult problems which caused by the difference in thermal behavior and viscosity and the core-sheath breakdown of the two polymers are solved. A series of technological data in spinning, drawing and heat setting are obtained and the fiber produced has been analysed in terms of structural properties, the result has guide meanings for producing PA/PP core-sheath composite fibers.更多还原
